These arrow frameworks show start and end points for a task or effort. Use these arrows when specific activity dates are not necessary or unimportant, although tick marks and measurement increments can be added (combine with series TO006 axes). These frameworks can also be used in place of a list of numbered/sequential items (or lists if you use the split arrows as in the example to the right).

This type of timing arrow isn't used very often because it takes a bit of effort to draw the starting point of the diagonal arrows so that they meet the axes correctly and don't hang over (as they do when using the arrow tool in PowerPoint).

Two framework versions in this series include leader lines. The example shows leader lines with a "ball" at the end (which can be created by formatting the line in PowerPoint). This type of chart requires leader lines. Be sure to decide on the look you want and stay with it for the sake of consistency. Also, choose a color for the leader lines that is prominent enough to do the job but does not compete with the primary information on the chart. Refer to the tutorial for specific formatting and animation techniques.
